Precision Cylindrical Roller Bearings

A: A special feature is that in addition to the mandatory components, e.g. inner ring, outer ring, rolling elements and cage, which are characteristic of every rolling bearing, cylindrical roller bearings can have additional lips.

A: Cylindrical roller bearings (CRBs) have a simple structure of cylindrical rollers in linear contact with the raceways. They offer high load capacity under primarily radial loads. Low friction between the rollers and ring ribs makes these bearings suited for high speed rotation.

A: Cylindrical roller bearings are designed to handle high radial loads and to moderate low axial loads. They have a higher load-carrying capacity than ball bearings due to their larger contact area, making them suitable for heavy-duty applications such as wind turbines and industrial machinery.

A: For small, non-separable ball bearings, hold the bearing horizontally in one hand, and then rotate the outer ring to confirm that it turns smoothly. Separable bearings such as tapered roller bearings may be checked by individually examining their rolling elements and the outer ring raceway.

A: As their name suggests, cylindrical roller bearings are cylinders that are arranged between the inner and outer races. These cylinders, which are shaped like soda cans, roll along their sides in the tracks of the races. The elements can only roll along a single axis, unlike balls which can roll in any direction.
